Symfony deprecation warning on grabService()

[ThomasLandauer]

This might be related to #4318

When calling $I->grabService() in a functional test, I'm getting this message:

The "XY" service is private, getting it from the container is deprecated since Symfony 3.2 and will fail in 4.0. You should either make the service public, or stop using the container directly and use dependency injection instead

• Codeception version: 2.3.7

[Naktibalda]

a) it isn't an issue,
b) have you tested if it works with Symfony 4.0 ?

[ThomasLandauer]

b) No, I haven't. The message is from Symfony 3.4.3. Do you think it will "disappear" in Symfony 4.0?

[Naktibalda]

At least it didn't break Doctrine module.

Finally fixed in Codeception 3.1.2 via #5706
